This invention relates'tm a collapsible tube winding and extruding keywhich is especially adapted-for use I inconjunction with collapsibletubes containingv toothpaste; shaving "cream; and

various other pastes; creams, "and like materials which aresold-in=collapsibl*tubes.

The; primary-object of the present invention is to provide a novelkeyforwindingand'extrum ing pastes, creams-or like-materials-fromcollapsible tubes.

Another-object of the present invention is to construct the new-key; insuch'a' manner-"that .it

maybe readily gripped and held in the hands of A preferred embodimentof'themewtspollapsible;'

A further-object of the invention is to "con:

struct the new=collapsible tube windingand eX- trudingkey in such-amanner thatthepivotally 20.11 connected together in any'suitable manner;as.

The use-andropera-tion .oi the.newtcollapsiblew tube winding andextruding key are as follows: The clamping jaws II and I2 may be spreadapart laterally, upon their pivotal connection I3, into the position inwhich they are illustrated in dotted lines in Fig. 2, whereupon thelower and relatively flat bottom end portion 24 of a collapsible tube25, containing cream, paste or like material, may be arranged in asubstantially vertical position between the two clamping jaws I I and I2which are at this time preferably disposed in a substantially horizontalposition, as in dotted lines, Fig. 2. The two clamping jaws II and I2may then be drawn together, upon their pivotal interconnection l3, andas they are thus drawn together the body l5 of the upper clamping jaw I2slides over the body M of the lower clamping jaw II so as to clamp theflattened bottom end portion 24' of the collapsible tube 25 between thetwo clamping jaws I I and I 2. As the two clamping jaws II and I2 arethus moved into effective or clamping position the latch openin 2| whichis formed in the latch portion I6 of the upper clamping jaw I2 comesinto registry with and above the latch element or stud I9 which iscarried by the lower clamping jaw I I, whereupon-the two clamping jawsII and I2 may be pressed together so that the latch portion 23, whichforms a part of the marginal edge of the latch opening 2|, willlatchingly engage under the latching flange 22 on the latch element orstud I9 and thus securely latch the two clamping jaws I I and I2together and against unintentional and undesirable separation or pivotalmovement relative to each other about their pivotal interconnection I3during the collapsible tube winding and extruding operation.

The collapsible tube rolling and extruding operation may then becompleted by manually grasping the finger grip or handle portions I1 andI8 of the clamping jaws II and I2 and winding the body of thecollapsible tube 25 therearound, gradually, as it is desired to extru'dethe paste, cream or like contents from the then open tube 25, as may beseen by reference to Figs. 4, 5 and 6 of the drawing.

After the contents of the collapsible tube 25 has been completelyextruded therefrom the then empty tube may be unwound or unrolled andthe key I removed therefrom by slipping the latching marginal edgeportion 23 of the latch opening 2I, which is formed in the body I of theupper clamping jaw I2, out of latching engagement with the latchingflange IS on the latch element or stud 22, and then manipulating theclamping jaws II and I2, about their pivotal connection I3, into openposition, as in dotted lines in Fig. 2.

It will be noted by reference to Figs. 1, 2 and 3, of the drawing thatthe latch opening H which is formed in the latch portion I6 of the upperclamping jaw' I2 is somewhat oval shape in plan form and is somewhatlarger in size, along its long axis, than the head of the latch elementor stud l9. This arrangement enables marginal edge portions of the latchopening H which is formed in the latch portion I 5 of the upper clampingjaw I2 to be slipped downwardly over the head of the latch element orstud I9 carried by the lower jaw II after which the latching marginaledge portion 23 of the latch opening 2I may be slipped under and intolatching engagement with the flange 22 which is formed on the head ofthe latch element or stud I9.

It will thus be seen from the foregoing description, considered inconjunction with the accompanying drawing, that the present inventionprovides a novel collapsible tube winding and extruding key, and thatthe invention thus has the desirable advantages and characteristics andaccomplishes its intended objects including those hereinbefore pointedout and others which are inherent in the invention.

5. A collapsible tube winding and extruding key as defined in claim 1 inwhich one of the said finger g-rip portions is formed integral with andextends approximately rightangularly from one of the said clamping jawsat one side thereof and in which the other of the said finger gripportions is formed integral with and extends substantiallyrightangularly from the other one of the said clamping jaws at theopposite side thereof from the side at which the said first-named fingergrip portion is arranged and in substantially parallel relationship tothe said first-named finger grip portion, and in which the said meansfor latching the said clamping jaws together includes a latch portionformed in one of the said clamping jaws and having a latch openingformed therein and a latch element mounted on the other of the saidclamping jaws and having a latch portion projecting above the said oneof the said clamping jaws and latchingly engageable in the said latchopening.

6. A collapsible tube winding and extruding key as defined in claim 1 inwhich one of the said finger grip portions is formed integral with andextends approximately rightangularly from one of the said clamping jawsat one side thereof and in which the other of the said finger gripportions is formed integral with and extends substantiallyrightangularly from the other one of the said clamping jaws at theopposite side thereof from the side at which the said first-named fingergrip portion is arranged and in substantially parallel relationship tothe said first-named finger gri portion, and in which the said means forlatching the said clamping jaws together includes a latch portion formedin one of the said clamping jaws and having a latch opening formedtherein and a latch element mounted on the other of the said clampingjaws and having a latch portion projecting above the said one of thesaid clamping jaws and latchingly engageable in the said latch opening,and in which the said latch element includes a laterally extendingflange and in which the said latch portion formed in the said one of thesaid clamping jaws includes a portion defining a part of the said latchopening and latchingly engageable under the said laterally extendingflange on the said latch element.
